| SmartThings | Yes | Shelly's spec table marks Samsung SmartThings capabilities as supported.[2] |
| Home Assistant | Yes | Official Shelly integration with local push.[4] |
“Via Matter” means you add it with that platform's Matter controller instead of a brand skill or app. “Unconfirmed” means we couldn't find an official source either way. How we verify.
